How ISO aperture and shutter speed are related?
The ISO controls the the amount of light by the sensitivity of the sensor. The shutter speed controls the amount of light by the length of time. The aperture (the size of the lens opening) controls the amount of light by the intensity via a series of different sized openings.
How do you match shutter speed and aperture?
The correct exposure will then also be achieved if you increase the f-number to f/5.6 while slowing shutter speed to 1/125 s. The same is true at f/8 and 1/60 s and at f/11 and 1/30 s. If you always adjust shutter speed to match any changes in aperture, you can achieve correct exposure at any aperture or shutter speed.
What is the right ISO to set?
Correct ISO Setting – Image Quality Whenever image quality is of the utmost importance, always shoot with an ISO 100 setting. Now remember in low light situations, this will mean your camera will also shoot much slower than if you used a faster ISO 800 for example.
When should I increase ISO?
You should only raise your ISO when you are unable to brighten the photo via shutter speed or aperture instead (for example, if using a longer shutter speed would cause your subject to be blurry).

Why are my DSLR pictures not sharp?
If your images are a bit soft, a bit blurry or a bit out of focus, it’s going to be one of only 3 reasons causing the problem – an autofocus issue, a depth of field issue, or a shutter speed issue. Try these troubleshooting steps before you take your camera to be looked at, if you think you have a sharpness problem.
Should I adjust ISO or shutter speed?
The reason you should change your ISO is because you’re targeting a specific shutter speed. The Milky Way is moving (at least, relative to us) which means, if you want to freeze it in place in your photo, you must use a shutter speed that will do just that. Otherwise it will turn out as a bunch of streaky stars.
